Executing the "Demo + Plugin version 0.2" link from your first post:
FF 10.0.2 on win7 pro 64 bits:
Firebug raises this:
Chrome 17.0.963.56 m
Console displays this:
2runtime.js:70 Uncaught TypeError: Object inst:t8#8 has no method 'Sa'
Your demos never worked on my browsers so far.
My graphic card drivers are up to date.
For both browsers, it displays the black background, the text and buttons, but it feels like the canvas is not even drawn.
It worked in IE 9.0.8112. A bit slow and not very good looking.
